Ah. hahahhaaha! We live on a finite world.
How can resources not be fixed?
Hahahaha!
Trees are "finite," but none of us seem to worry about not having enough for paper. Not to mention, even though trees are finite, we have plenty of people who intentionally grow trees in order to make a living. In other words, we have many trees precisely because people value trees enough to pay others to plant them.
Likewise, we have plenty of cows, horses, cats, dogs, etc, precisely because people can have property rights on these animals and that people can make some profit off of them. In fact, the problem with many endangered species is that it's illegal to own them (in other words, there are no property rights for them).
What about food? Isn't corn, milk, wheat, strawberries, etc finite? However, are you worried about their not being enough to go around? Drugs such as tobacco and marijuana are finite. Do you think that people will quit smoking these in the next couple hundred years because there is not enough to go around?
Notice that "natural" and "finite" are not the same thing as "fixed" (in other words, "natural" and "finite" can still be "variable"). Notice that human beings are able to control (at least to some degree) the amount of many natural resources.
Yes, with oil there are some differences. However, it has also been pointed out that there are many untapped oil reserves. Why has no one decided to get this oil out of the ground in some places? Precisely because it is "not worth it" (yet) to do so. Some oil reserves are more expensive to extract, and therefore the current payoff is not high enough to warrant extracting it. As oil becomes more and more scarce, and if consumers are demanding it at nearly the same rate, then the price will rise enough in order to actually make it profitable to extract the oil at these places. I am under the impression that the statistics that you cite (which state that oil will be gone in 50 years) make some mistakes. For one thing, I think they don't account for all of the untapped oil reserves. Furthermore, they assume that people will use oil at the exact same rate. Oil is obviously running out, however I just don't know how accurate the 50 years stat is.
To put it briefly, I'm just not as worried as you are about the oil situation. First of all, if oil is quickly depleting then prices will rise and people will surely substitute away from oil. For example, people will move closer to work, carpool more, ride their bike more, use public transportation more, drive less often for entertainment reasons, etc. Second, if oil is becoming more and more expensive, entrepenuers will surely be able to make very large profits by inventing alternatives. In other words, you're likely to see some great innovation in this industry.
